This expression cannot be simplified because you cannot take any common factor outside the root.
Is it equivalent? please show work so i can write it
No, because
2(y + 1,5) = 2 · y + 2 · 1,5 = 2y + 3
2y + 3 ≠ 2y + 1,5
Answer:
No
Step-by-step explanation:
2 ( y + 1.5 ) = 2y + 3. Not 2y + 1.5
Mrs. Helton is making gift bags as prizes for her math classes. She has 30 little bags of Hershey Kisses and 15 Blow Pops. What is the greatest number of gift bags she can make if all gift bags are the same, and she does not want any left over?
Answer:
15
Step-by-step explanation:
For this we must find the GCF, or greatest common factor, because we cannot have multiples.
Factors of 30:
1 , 2, 3, 5, 6, 10, 15, 30
Factors of 15:
1, 3, 5, 15
GCF = 15
Each bag will have 2 Hershey bags, and 1 Blow Pop

Answer:
Step-by-step explanation:
Please help explanation if possible
Answer:
y = 4x-31
Step-by-step explanation:
parallel lines, slope is the same.
two ways to solve it,
y=4x+c
sub y = -11. x =5
-11 = 4(5) + c
c = -31
OR
y-(-11) = 4(x-5)
y+11=4x-20
y=4x-20-11
y=4x-31
Answer:
The equation is y = 4x - 31
Step-by-step explanation:
y - y1 = m (x - x1)
y - (-11) = 4 (x - 5)
y + 11 = 4x - 20
y = 4x - 20 -11
y = 4x - 31
Find the slope intercept form and the point slope the line perpendicular to 4x-7y=2 going through (-6,1)
Answer:
Slope-intercept form: [tex]y=-\frac{7}{4}x-\frac{19}{2}[/tex]
Point-slope-form: [tex]y-1=-\frac{7}{4}(x+6)[/tex]
Step-by-step explanation:
Hi there!
We want to find the equation of the line perpendicular to the line 4x-7y=2 that goes through (-6, 1) in slope-intercept form, as well as the point-slope form
Slope-intercept form is defined as y=mx+b, where m is the slope and b is the y intercept
Point-slope form is defined as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
Meanwhile, perpendicular lines have slopes that are negative and reciprocal. When they are multiplied together, the result is -1
So let's find the slope of the line 4x-7y=2
The equation of the line is in standard form, which is ax+by=c, where a, b, and c are integer coefficients a is non-negative, and a and b aren't 0
So let's find the slope of the line 4x-7y=2
One way to do that is to convert the equation of the line from standard form to slope-intercept form
Our goal is to isolate y onto one side
Subtract 4x from both sides
-7y=-4x+2
Divide both sides by -7
y=[tex]\frac{4}{7}x-\frac{2}{7}[/tex]
So the slope of the line 4x-7y=2 is [tex]\frac{4}{7}[/tex]
Now, we need to find the slope of the line perpendicular to it
Use this formula: [tex]m_1*m_2=-1[/tex]
[tex]m_1[/tex] in this case is [tex]\frac{4}{7}[/tex]
[tex]\frac{4}{7}m_2=-1[/tex]
Multiply both sides by [tex]\frac{7}{4}[/tex]
m=[tex]-\frac{7}{4}[/tex]
Let's see the equation of the perpendicular line so far in slope-intercept form:
y=[tex]\frac{-7}{4}x[/tex]+b
We need to find b now
The equation of the line passes through (-6,1), so we can use it to solve for b.
Substitute -6 as x and 1 as y
[tex]1=-\frac{7}{4}*-6+b[/tex]
Now multiply
1=[tex]\frac{42}{4}+b[/tex]
Subtract 42/4 from both sides to isolate b
-19/2=b
Substitute -19/2 as b into the equation
The equation in slope-intercept form y=[tex]\frac{-7}{4}x-\frac{19}{2}[/tex]
Now, here's the equation in point-slope form
Recall that the slope is [tex]\frac{-7}{4}[/tex] , our point is (-6, 1), and point-slope form is [tex]y-y_1=m(x-x_1)[/tex]
Let's label the value of everything to avoid any confusion
[tex]m=-\frac{7}{4} \\x_1=-6\\y_1=1[/tex]
Now substitute those values into the equation
[tex]y-1=-\frac{7}{4}(x--6)[/tex]
We can simplify the x--6 to x+6
[tex]y-1=-\frac{7}{4}(x+6)[/tex]
Hope this helps!

What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
We have to find the midpoint of the line joining the two points (2, 4) and (2, -9)
Midpoint = (x₁+x₂/2, y₁+y₂/2)
x₁ = 2, y₁=4, x₂ =2 and y₂ = -9
We have to plug in the values in the above formula
Midpoint = (2+2/2, 4-9/2)
Midpoint = (6/2, -5/2)
=(2, -5/2)
Hence, the midpoint of the vertical line segment in the graph is (2, -5/2)

Answer:
y+11=-[tex]\frac{1}{4}[/tex](x-4)
Step-by-step explanation:
since the equation is perpendicular to y=4x-2, m=-1/4 (negative reciprocal). (x_1,y_1)=(4,-11), plug all the values into the equation y- y_1 = m(x-x_1) and we get y+11=-[tex]\frac{1}{4}[/tex](x-4)
Let a and b be numbers. Use the distributive law to rewrite the expression in a simpler form. a(a+b) =
Answer:
Distributive law, in mathematics, the law relating the operations of multiplication and addition, stated symbolically, a(b + c) = ab + ac; that is, the monomial factor a is distributed, or separately applied, to each term of the binomial factor b + c, resulting in the product ab + ac. From this law it is easy to show that the result of first adding several numbers and then multiplying the sum by some number is the same as first multiplying each separately by the number and then adding the products.
Step-by-step explanation:
a(a+b)
in this question first a will multiply by a+b.
like this;
a(a+b)
= a(a)+ab
= a^2+ab
The simpler form of the expression a(a + b) is [tex]a^2 + ab.[/tex]
Distributive law states that for any numbers a, b, and c :
a(b + c) = ab + ac
Expression: a(a + b) rewrite it using the distributive law to simplify it.
1. Start with the expression a(a + b).
2. Apply the distributive law by multiplying the 'a' outside the parentheses by each term inside the parentheses:
a(a + b) = a * a + a * b
3. Simplify by multiplying:
a(a + b) = [tex]a^2 + ab[/tex]
Therefore, the simpler form of the expression a(a + b) is [tex]a^2 + ab.[/tex]
